Abstract: An organic light emitting display (OLED) device includes a substrate including a light emitting region and a peripheral region. An auxiliary power supply wire is disposed in the peripheral region. A lower electrode is disposed in the light emitting region. A pixel defining layer, disposed on the substrate, exposes a portion of the lower electrode and a portion of the auxiliary power supply wire. A first common layer, disposed on the pixel defining layer and the lower electrode, exposes the auxiliary power supply wire. A light emitting structure is disposed on the first common layer. The light emitting structure exposes the auxiliary power supply wire. A second common layer is disposed on the light emitting structure, the second common layer covering the light emitting structure and exposing the auxiliary power supply wire. An upper electrode is disposed on the second common layer and contacts the auxiliary power supply wire.

Abstract: A pixel includes first through sixth transistors and an organic light emitting diode. The first transistor includes a gate electrode connected to a first node, a first electrode, and a second electrode connected to a second node. The second transistor provides a data signal to the first node in response to a scan signal. The third transistor provides a first power voltage to the first transistor in response to an emission control signal. The fourth transistor provides a reference voltage to the first node in response to a voltage control signal. The fifth transistor provides the reference voltage to the first node in response to an initialization control signal. The sixth transistor provides an initialization voltage to the second node in response to the initialization control signal. The organic light emitting diode is connected between the second node and a second power voltage.
